base 12 fan here. more precision for almost every type of calculation humans need to do regularly. maybe i could be persuaded to say base 60 is better, like the old babylonian math but 2 and 3 as the base factors gets you most of the way. base 60 makes it track with the resonances of base 10 as well, which is 2 and 5, but i've tinkered with this and ternary math is provably more efficient also for cryptography especially when using bethe lattices
